2 Asymmetric multiprocessing 1 Asymmetric multiprocessing https://store.theartofservice.com/the-symmetric-multiprocessing-toolkit.html

3 Asymmetric multiprocessing 1 In an asymmetric multiprocessing system, not all CPUs are treated equally; for example, a system might only allow (either at the hardware or operating system level) one CPU to execute operating system code or might only allow one CPU to perform I/O operations https://store.theartofservice.com/the-symmetric-multiprocessing-toolkit.html

4 Asymmetric multiprocessing - Univac 1108-II 1 The Univac 1108-II and its successors had up to three CPUs. These computers ran the UNIVAC EXEC 8 operating system, but it is not clear from the surviving documentation where that operating system was on the path from asymmetric to symmetric multiprocessing. https://store.theartofservice.com/the-symmetric-multiprocessing-toolkit.html

5 Asymmetric multiprocessing - Notes 1 VAX Product Sales Guide, pages 1-23 and 1-24: the VAX-11/782 is described as an asymmetric multiprocessing system in 1982 https://store.theartofservice.com/the-symmetric-multiprocessing-toolkit.html

6 Symmetric multiprocessing 1 Symmetric multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors connect to a single, shared main memory, have full access to all I/O devices, and are controlled by a single OS instance that treats all processors equally, reserving none for special purposes https://store.theartofservice.com/the-symmetric-multiprocessing-toolkit.html

7 Symmetric multiprocessing - Entry-level systems 1 With the introduction of ARM Cortex-A9 multi-core SoCs, low-cost symmetric multiprocessing embedded systems began to flourish in the form of smartphones and tablet computers with a multi-core processor. https://store.theartofservice.com/the-symmetric-multiprocessing-toolkit.html

8 NetBSD - Symmetric multiprocessing 1 NetBSD has had support for Symmetric multiprocessing|SMP since the NetBSD 2.0 release in 2004, which was initially implemented using the giant lock approach https://store.theartofservice.com/the-symmetric-multiprocessing-toolkit.html
